debug/elf: support zstd compression

2023-04-18T20:34:36+00:00

Test cases added to debug/dwarf because that is where it matters in practice.

The new test binary line-gcc-zstd.elf built with

    gcc -g -no-pie -Wl,--compress-debug-sections=zstd line[12].c

using

    gcc (Debian 12.2.0-10) 12.2.0

with a development version of the GNU binutils.

Fixes #55107

all: re-run stringer

2023-04-11T20:24:07+00:00

Re-run all go:generate stringer commands. This mostly adds checks
that the constant values did not change, but does add new strings
for the debug/dwarf and internal/pkgbits packages.

debug/dwarf: don't crash on negative range/rnglist offset

The struct in the doc comment in debug/dwarf/type.go
was fixed up by hand to indent the first and last lines as well.

For #51082.
